Special compound feed for native pigs and preparation method thereof

Abstract

The invention relates to special compound feed for native pigs and a preparation method thereof. The special compound feed comprises the following raw material components in parts by weight: 500-600 parts of corn, 35-45 parts of bean meal, 55-65 parts of puffed soybeans, 35-45 parts of peanut cakes, 30-50 parts of oil sunflower cakes, 25-35 parts of oil flax cakes, 60-70 parts of alfalfa meal, 75-85 parts of millet bran, 55-56 parts of dried red jujubes, 9-11 parts of stone powder, 6-8 parts of calcium hydrogen phosphate, 4-6 parts of compound trace elements, 2-4 parts of sodium chloride, 2-3parts of lysine hydrochloride, 0.2-0.4 part of vitamin complex, 0.1-0.3 part of selenium yeast and 1-3 parts of a 0.2% compound premix. The preparation method adopts the cakes and meal with high fat content as raw materials and intensifies the components such as fat-soluble vitamins and amino acids, and the prepared special compound feed for native pigs is favorable for growth of muscle tissues and deposition of aroma-producing substances and improves the meat quality and pork flavor.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a special compound feed for native pigs and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards in recent years, more and more consumers have reported that the pork on the market now tastes less and less fragrant and tasteless, without the aroma and taste of pork raised in rural areas in the past. After years of research and a large number of feeding experiments, it was found that: (1) in the traditional breeding mode of soil pigs, the pigs are fed with bran and miscellaneous green grass, leaves, plant roots and other natural fresh green feed as staple food, which objectively supplements the pigs. Increase the pork-flavored amino acids, vitamins and fibers in a large amount, and then feed a large amount of high-fat oil cake agricultural by-products during the fattening period, increasing the pork-flavor...

AI Technical Summary

Problems solved by technology

However, the current feed raw material processing technology has undergone tremendous changes from the original pressing to the extraction technology, making the fat content of agricultural and sideline products lower than in the past, forming low-energy and high-protein, which is beneficial to the growth of pigs, but not conducive to the deposition of fat in muscle tissue.

(2) After large-scale breeding, due to the change in the structure of the diet, the time from birth to slaughter has been shortened from about 1 year before to 5-6 months now, and the growth rate has accelerated and lean meat has increased, but it has affected the preserved meat. Precipitation and accumulation of aroma substances such as amino acid, sarcosine, nucleotides and fat in the meat quality, the fat content in pork is less, which affects the flavor of pork

(3) Native pig breeding is fed with conventional pig feed on the market, while conventional pig feed on the market is formulated for foreign breed pigs. Growth-promoting agent, long-term feeding, will affect the local pork flavor and meat color, etc.
